我有一个功能可以在 Twitch 上生成某个用户的所有视频 URL

def get_videos(cursor=None):  # functiont to retrieve all vod URLs possible, kinda slow for now
    params_get_videos = {('user_id', userid_var)}  # params for request.get
    if cursor is not None:  # check if there was a cursor value passed
        params_get_videos = list(params_get_videos) + list({('after', cursor)})  # add another param for pagination
    url_get_videos = 'https://api.twitch.tv/helix/videos'  # URL to request data
    response_get_videos = session.get(url_get_videos, params=params_get_videos, headers=headers)  # get the data
    reponse_get_videos_json = response_get_videos.json()  # parse and interpret data
    file = open(MyUsername+" videos.txt", "w")
    for i in range(0, len(reponse_get_videos_json['data'])):  # parse and interpret data
        file.write(reponse_get_videos_json['data'][i]['url'] +'\n')  # parse and interpret data
    if 'cursor' in reponse_get_videos_json['pagination']:  # check if there are more pages
        get_videos(reponse_get_videos_json['pagination']['cursor'])  # iterate the function until there are no more pages

这本身就可以很好地工作(与其他功能一起使用),但是每当我尝试从这样的虚拟烧瓶服务器调用它时

from flask import Flask
from flask import render_template
from flask import request
from main import *

app = Flask(__name__)

@app.route('/')
def hello_world():
    return render_template("hello.html")

@app.route('/magic', methods=['POST', 'GET'])
def get_username():
    username = request.form.get('username')
    get_videos()
    return ("Success")

它不再递归,只打印前 20 个值。我究竟做错了什么?

我也是新手,所以我没有足够的声誉发表评论,我必须发布答案。我对您的 get_username 方法感到困惑,一旦您从表单中获取用户名,您就不会将其发送到任何地方?看起来在您的 get_videos 方法上,您可能通过在此方法之外保存一个名为 MyUsername 的变量来对用户名进行硬编码?

你应该做的是发送你从表单中获取的用户名,像这样执行你的 get_videos 方法。

get_videos(用户名)

并将您的其他方法更改为此 def get_videos(MyUsername, cursor=None):
